🔖 chore: 0.4.1 — the published README says the package is not on npm

The README inside a tarball is what npmjs.com renders, so the cereale package
page currently tells visitors: "npm install cereale does not resolve to this
library — the name is unclaimed on the registry." True when it was written,
nonsense on the page of the thing it describes.

Nothing could have prevented it. 0.4.0 was the first publish, so the docs could
only be corrected after the registry proved the claim wrong; the fix has to
ride a second version.

No code changes. Every emitted file is byte-identical to 0.4.0 except the
banner line of dist/cereale.min.js, which carries the version string — checked
by unpacking the published 0.4.0 tarball and diffing it against a fresh pack,
which is also why the changelog no longer claims dist/ is untouched. It said
that first, and it was wrong.

Patch rather than minor: no API surface moves.
